A lawnmower is a livestock machine that can cut pasture or other crops that can be made into hay and lay it on the ground.
Concept
Before the 19th century, people used long-handled scythes to cut grass. It is a laborious job and requires many skills to keep the grass short.
A British engineer named Thomas Plunkett was the first person to come up with the idea of ??making a lawn mower. He patented the first lawn mower in 1805. It was a heavy machine with a ring blade, and it didn't work very well. Other inventors saw Plunknet's machine and thought they could do a better job. The most successful was Erwin Bardeen. He was an engineer in a textile factory and got the idea for the mechanical structure of a lawn mower from a piece of machinery in the factory. The lawnmower he built in 1830 was very similar to those machines used today. The large yard with its undulating terrain and numerous surface obstacles poses a huge challenge to the engine's performance. The Vanguard engine is suitable for lawn tractors and can undertake tasks such as raking, carrying, pulling, plowing, tilling and hoeing.
Overview
Forage harvesting machinery that cuts pasture or other crops that can be made into hay and lays it on the ground. There are two types: reciprocating type and rotary type. Reciprocating lawn mowers were used in production in the late 1850s. They were initially pulled by animal power and the cutter was driven by ground wheels. Tractor-pulled lawn mowers began to be developed in the early 20th century. After the 1920s, the power output shaft was used to drive the cutter. In the 1930s, tractor-mounted reciprocating lawn mowers began to be developed. In the mid-1960s, rotary lawn mowers were developed. China began to use animal-powered reciprocating lawn mowers in the 1920s. In the early and late 1950s, it began to produce animal-powered and tractor-pulled reciprocating lawn mowers. With the development of artificial grass fields, the production and use of rotary lawn mowers began in the mid-1970s. In countries where animal husbandry mechanization is highly developed, research on new lawn mowers is developing in the direction of high speed and energy saving.
